How much does the Chevy SB2 have in common with a pickup truck 350? Lets find out! The small block Chevy as it were found in a pickup truck made its way in modified form to NASCAR racing in the early 1970's. Today they are still the same 350 cubic inch displacement but the entire engine shares no factory parts whatsoever. How did we get here from "stock" cars? Keith Dorton has been building NASCAR engines since the 1960's and has every iteration of the evolution for us to see. From the bowtie heads to the Pontiac Brodix 867s to the legendary SB2 into the current Chevrolet Performance R07 engine used in NASCAR today!
